I'm sure this has been mentioned here somewhere else, but it's definitely worth its own thread. Note that the $110m is for the first stage of lengthening and widening the jetty:

A HOTEL floating above the Glenelg jetty and with ocean views across the horizon is the centrepiece of a $110 million development aimed at reinvigorating the foreshore.

The Advertiser has obtained plans for a long-discussed revival of the Glenelg landmark from designers Mott MacDonald, which requires government funding to get the green light.

SA Liberal leader Steven Marshall will today announce that his party will commit $20 million to the project if it wins the next election and a cost-benefit study shows an overall economic lift.

The development plan was kickstarted by the Jetty Road Mainstreet Committee in 2014 with cash for the concept design and further money has been allocated for an economic analysis.

The plan includes doubling the length of the jetty and widening it to six times its current size at a cost of $110 million. That base would be used for the private development of a boutique hotel, dock for a fast ferry to Kangaroo Island, marine research centre, restaurants and public space.

“This type of project is how governments should be growing the economy,” he said.

“The State Government should be backing private investors who want to create jobs, renew our state and grow our economy. “Glenelg is a great location but it needs a refresh. This development will breathe life into the area.”

The state Liberals would provide $20 million towards the jetty redevelopment if there were a positive cost-benefit analysis and federal government funding contribution, Mr Marshall said.

Federal Liberal Hindmarsh MP Matt Williams is facing a strong Labor challenge for his seat at an election due on July 2. Mr Williams said he supported the project.

The Jetty Road Mainstreet Committee wants to return the jetty to its heyday of the early 1900s when it housed city baths, tea house and aquarium.

They were washed away in a storm in 1948 and the current jetty was built in 1969.

Holdfast Bay Mayor Stephen Patterson said state and federal government support and financial commitments would help attract private investors needed.

A state government spokeswoman said: “The Government is yet to hear from the proponents of the Glenelg Jetty plans but we would be happy to consider the proposal once we do”.

Love the concept, especially the idea of a hotel as part of the development, which would provide the foot traffic required for this to be successful and remove one of my concerns with such a development.

I know the Ferry to KI service from Glenelg has been floated and shot down before (didn't they use to provide this service many years ago?) but this vision would surely help in potentially making it a viable service.

And a big thumbs up to the marine research centre as well! For a State like ours, where the commercial marine industry represents such a large part of our economy, we need something centralized like this to show off what we have to offer.

Looks incredibly ambitious but that's what we need right now - can't wait for the Glenelg residents association (whatever they're called) to weigh in on this one... "the jetty is a historic landmark [since 1969]"...

If this went ahead, even minus the ferry dock part, it would still be enough to create one of those 'must see/visit' tourist things that SA is always accused of not having enough of - and perfectly aligned with the existing tram line to make it accessible for tourists as well as locals.

The hotel is key — it would be a destination hotel (people would come to Adelaide/Glenelg specifically to stay there).

Who is up for the cash though? Libs say they'll chip in $20m, but who then is responsible for the rest? If it's private investment, will the new jetty be given to the public or will the entire structure become privately owned?

The Libs aren't going to contribute shit.
Read the rest of that sentence. They've given them selves an escape clause.
Their claim they'll put up 20 million if they win the election is just a way to get people to vote for them.
They've been against every positive development in this state for years, they've come up with no plans or visions, just a hollow plan with no substance, and now suddenly they'll fund tourist infrastructure? Give me a break. They aren't trying very hard.

From the images it seems part of this will be below the water? I guess with the natural movement of sand already disturbed it wont make much of a difference hell it may even make things better
